longer necessary since read_key_sequence doesn't modify these
events for internal purposes anymore.
(isearch-lazy-highlight-regexp): New variables.
(isearch-lazy-highlight-cleanup): Update lazy highlight if
case-fold search or regexp search has been toggled.
1 here rather than each time through
isearch-lazy-highlight-new-loop.

behavior folded into isearch-lazy-highlight-cleanup. "Keep"
behavior removed.

isearch-lazy-highlight-update in a loop rather than just once.

loop, rather than testing it each time through

(isearch-lazy-highlight-update): Get called in a timer loop again,
but this time highlight more than one match each time through.
Only highlight matches in the visible part of the window. Start
at point, move in the direction of the search, and wrap around at
the edge of the window. Use sit-for to force redisplay and ensure
window-start is credible. "Face suppressing" behavior removed;
overlay priorities should make it unnecessary, right?
(isearch-highlight): Face suppressing behavior removed.

(isearch-lazy-highlight-cleanup): Arg now says
to remove all the current alternative-match highlighting.

region within which NOT to remove them.
(isearch-lazy-highlight-new-loop): Greatly simplified.

(isearch-mode): Set `minibuffer-message-timeout' to nil, after
stashing away its original value.

(isearch-highlight): Restore lazy-isearch face properties at old
position, and suppress them at new position.
(isearch-dehighlight): Restore lazy-isearch face properties.
(isearch-lazy-highlight-update): Add lazy-isearch overlays even
over the real isearch overlay, but in that case, don't give it a
face property. Use `push'.
highlighting overlay with a different face over the overlay
isearch uses to highlight the current match because that can lead
to bad face combinations.
(isearch): New defface; was already tested for in the code.
(isearch-lazy-highlight-face): Changed to defface from defcustom.

to prevent the point moving to the end of a composition when a
part of a composition is searched.
